Table 3 Number of interventions for intracranial hypertension

From: The relationship between serum sodium and intracranial pressure when using hypertonic saline to target mild hypernatremia in patients with head trauma

  Mean serum sodium P value
  < 145 mEq/l 145 to 155 mEq/l > 155 mEq/l  
Day 1 4.35 ± 2.33 4.31 ± 2.02 2.00 ± 0 0.354
Day 2 4.16 ± 2.73 2.67 ± 1.39 3.00 ± 0 0.033
Day 3 5.12 ± 3.97 2.91 ± 1.82 3.17 ± 3.49 0.018
Day 4 3.60 ± 3.50 3.41 ± 2.59 2.33 ± 2.00 0.527
Day 5 3.19 ± 2.44 1.84 ± 0.90 2.67 ± 1.53 0.043
Total 4.20 ± 2.91 2.95 ± 1.97 2.62 ± 2.25 < 0.001
  1. Data presented as mean ± standard deviation number of interventions per day, providing a summary of the mean number of interventions for intracranial pressure control on days 1 to 5. Patients were divided into three groups based on their mean serum sodium value on each day of the study period. For each day, statistical comparisons were performed for the number of interventions required in each group.
